KOSHER means "fit" or "proper" and is derived from Es ther viii. 5, the only biblical instance of the adjective, KOsHiR (Ashkenazie form, with accent shifted vulgarly, common in N. Europe) or KAsHiR (Sephardic form, common in S. Europe and the East). Kosher is chiefly used in connection with the dietary laws and implies (a) that the food is not derived from the animals, birds or fish prohibited in Leviticus xi. or Deut. xiv., (b) that the animals or birds have been slaughtered by cutting the windpipe (Shehitah) so as to produce instantaneous loss of consciousness, (c) that the meat has been salted (Melihah) to remove the blood (Deut. xii. 16, 23-25 and elsewhere) after the carcass has been critically examined (Bediqah) for physical blemishes, that the ischiatic nerve has been removed (porged) from hindquarters (Gen. xxxii. 32) and (d) that meat and milk have not been cooked together (Exod. xxiii. 19) and that separate utensils have been employed. Further information on these subjects will be found in Jew. Enc. s.v. Dietary Laws. For the Jewish mode of slaughter see Dr. M. Hyamson's pamphlet and the reports of Profs. Wood, Hill, Barcroft and Mr. L. F. Newman. In consequence of (b) the term Terefah (that which has been torn by beasts, Gen. xxxi. 39) is extended to all food violating the law, even, incorrectly to admixtures of leaven on Passover (Exod. xii. 2o), though Kosher cal Pesali, "fit for Passover" is fairly correct. So-called Kosher wine is wine grown and prepared under observation, to prevent libations from being taken from it. On this relic of Roman days, once common to Judaism and Christianity, see W. Elmslie's edi tion of Mishnah `Aboda Zara 09'0 in which the Jewish and Christian regulations (those of Tertullian) are compared. Kosher
is often used generally of other matters : sometimes as opposed to Pas (unfit), e.g., of a scroll of the Law.
